AUTOMATIC RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 514,795, dated February13, 1894. Application filed January 6, 1893. Serial No. 457,528- (Nomodel.)

To all whom it may concern:

Beit known that I, GOVERNOR D. WARREN, of Dallas, in the county ofDallas and State of Texas, have invented certain new and usefulImprovements in Automatic Railway- Gates; and I do hereby declare thefollowing to be a full, clear, and exact description of the nvention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being bad to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in automatic railway gates; andit consists in 1 view partly in section.

p and journal box.

the novel combination and arrangement of parts which will be'fullydescribed hereinafter, and more especially referred to in the claimhereto annexed.

Referring to the accompanying drawings, Flgure 1 is a plan view of atrack showing mylmproved gate applied thereto. Fig. 2 is a sideelevation of the same. Fig. 3 is an end Fig. 4 is a detached yiew of thecenter oscillating shaft. Fig. 5 1s a slmilar View of the combined railbrace Fig. 6, is a detail perspect1ve v1ew of one of the guide andsupporting castings located beside the rail showing the pivoted arms orcrank shaft therein, and in dotted lines showing the movable railsoperated by the car wheels.

A, designates the main rails, B, the cross ties and O, the longitudinalties or beams located beneath the gate.

Journaled beneath the rails A, and upon the beams O, is the shaft D, andprojecting from the latter upward along the outer sides of the rails A,are the double arms E.

Near the respective ends of the shaft 0, are the studs F, and F, whichrespectively extend above and project beneath the said shaft. Secured attheir inner ends to these studs are the, oppositely extending coiledsprings G,

which latter may be secured at their outer ends to the cross ties B, orbeams O, as desired. These springs counteract each other and inconsequence hold the shaft D. nor.- mallyin one position. Now thepickets H, of the gate, preferably formed of sheet steel, are secured tothe shaft D, so as to extend vertically with the said shaft in itsnormal position.

For automatically operating the gate by a train approaching in eitherdirection a rail I, is extended outward on each side of the gate, thesame being located on the outer sides of the respective tracks andloosely secured at their inner ends to the arms E, of the shaft D. Theserails incline toward their outer ends so that at the latter points theyare substantially flush with the main tracks. Suitably secured to thecross ties at intervals between the ends of the rails I, are thecastings J having a bed plate or portion K, extending beneath the bottomof the 'rail which at its inner end is bent upward to grasp the railflange brace for the same. From the outer end of this casting projectsthe wall L, having a countersunk inner side L, and between this wall andthe rail works the arm M, having a journal N, atits lower end mounted insuitable boxings in the bed plate K. Eyes 1, depending from rails I, areloosely connected to the upper ends of these arms. By this constructionthe rails I, are held securely in the desired position. The innerrecessed side L of the wall forms a guide as well as a portion of thecovering for arm M.

Journaled upon the cross ties at the ends of the movable rails I, aretheshort shafts 0, having projecting studs 0', to which the said rail endsare loosely secured and at the outer ends of these shafts are the crankarms P, to which the coiled springs Q, are connected, which latter therails pull against when moving forward to open the gate. A head R, isformed on oneend of the shaft D, adapted to receive a wrench S, for thepurpose of turning the gate down by hand when so desired. The wrench ishooked at its outer end to engage a ring secured to the track in aconvenient position so that the gate may be held down as long asdesired.

In operation an approaching train engages the outer end of the rail I,and in depressing it-swings it forward on its arms M, and thelongitudinal movement of the rail thus secured is sufficient to push thecrank arms E, of the shaft D, into a substantially horizontal positionthus acoomplishin g the oscillation of the latter and the lowering ofthe gate beneath the rails A, out of the way of the passing train. Theoperating rails are preferably thus forming a secure operate the same.

extended about sixty feet in each direction from the gate so as toafford ample room to After the train has passed entirely over the railsit Will be readily understood that the several springs willautomatically return the gate to its normal position. If from any causethe automatic operation should fail the pickets being formed of flexiblesteel will simply be pushed over by the passing train only to springback again when the latter has passed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the picket shaft extending beneath the rails andprovided with the upwardly extending cranks between the rails, springsyieldingly holding said shaft,

the tread rails extending along the rails, as described, and at theirinner ends pivotally joined to the said cranks, a series of stationaryguide blocks extending up beside each tread rail, the series of arms attheir upper ends loosely joined to a tread rail, said arms beingjonrnaled at their lower ends in said guide blocks and shielded thereby,and spring held crank shafts to which the outer ends of said tread railsare journaled, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

GOVERNOR D. WARREN.
